Press Release Summary:

April 30, 2013 -
Available in 0201–2220 SMT case sizes as well as with radial and axial leads, TransGuardÂ® Series has 3.3–85 Vdc working voltage range. AEC-Q200-qualified TransGuardÂ® Automotive Series, offered in 0402–2220 SMT case sizes as well as with radial leads, has 5.6–85 Vdc working voltage range, multi-strike capability, and 1 nS response to ESD strikes. Both series are based on zinc-oxide varistor technology and feature high-energy, monolithic multilayer construction.

AVX Adds Several New Varistors to Its Trusted Transguard® & Transguard® Automotive Series

GREENVILLE, S.C. — AVX Corporation, a leading manufacturer of advanced passive components and interconnect solutions, has added several new varistors to its trusted TransGuard® and TransGuard® Automotive Series. Based on AVX’s reliable zinc-oxide varistor technology, the extended TransGuard series provide customers with a much broader range of voltage and energy rating options than were previously available, significantly expanding both the number and type of applications for which the series are an ideal solution.

Both AVX’s TransGuard® and TransGuard® Automotive series varistors feature a unique, high-energy, monolithic multilayer construction that provides state-of-the-art circuit protection from voltage transients caused by ESD, lightning, inductive switching, automotive related transients, and other disruptions. The two TransGuard series also feature non-linear, bi-directional voltage-current characteristics similar to those of back-to-back zener diodes, but with the added advantage of greater current and energy-handling capabilities, as well as EMI/RFI attenuation. Lead-free and RoHS compliant, both series are designed for use in temperatures ranging from -55°C to +125°C.

“Demonstrating only negligible degradation in breakdown voltage and minimal increases in leakage current after repeated high-current pulsing, TransGuard® Series varistors consistently outperform the competition and have thus been very well-received,” said Jiri Machanicek, Technical Marketing Manager at AVX. “Consequently, AVX has extended both series with additional voltage and energy rating options designed to provide an even broader range of applications with trusted transient voltage suppression solutions.”

AVX’s TransGuard® and TransGuard® Automotive Series varistors exhibit a peak current up to 2000A, transient energy up to 12J, and low leakage currents under standard DC operating conditions. Both series are also available with Ni/Sn-plated terminations for lead free soldering or with Pd/Ag terminations for hybrid assembly.

TransGuard® Series varistors are available in 0201 to 2220 surface-mount case sizes, as well as with radial and axial leads. Exhibiting a working voltage range of 3.3–85VDC, the series is ideal for a wide range of professional, industrial, and commercial applications.

TransGuard® Automotive Series varistors are available in 0402 to 2220 surface-mount case sizes, as well as with radial leads. Featuring a working voltage range of 5.6-85VDC, the AEC-Q200-qualified series exhibits high current and high energy handling capabilities, multi-strike capability, and 1nS response to ESD strikes, which makes it extremely well-suited for protecting against automotive transients in wide range of applications, including: safety devices (airbags, ABS, etc.), body electronics (ECU, sensors, etc.), drive train (water pump, power steering, etc.), comfort and convenience (electric mirror, audio, etc.), and hybrid and electric engines (engine start/stop, electric drive, etc.).
